Terror threat’ against Heathrow-to-US flight

A minister has said “all steps necessary to keep the public safe” are being taken after a threat was reportedly made against Heathrow Airport. An alert from non-governmental counter-terrorism organisation SITE Intelligence Group on Friday warned of a threat being made by a “pro-Islamic State Twitter account”.

It is reported to have threatened attacks on planes “flying from Heathrow to the US” across the July 4 US Independence Day holiday weekend.

The alert also warned “there will be a device placed in either Heathrow, LAX or JFK airports”. Transport minister Lord Ahmad of Wimbledon called for the public to be cautious.

He said: “We all need to be vigilant to the global threat of terrorism – in the UK we keep all aspects of aviation security under constant review and work closely with our international partners to mitigate risks.

“We will continue to take all steps necessary to keep the public safe, but for security reasons we do not comment in detail on specific measures or operational matters.”

Heathrow Airport declined to comment on the apparent threat and referred inquiries to the Department for Transport.

On Saturday IS said it carried out a deadly attack on a restaurant in the Bangladeshi capital Dhaka.
